<br />x = 20605.6 = 3.9 mi <br />c <br />Sh = 25.20 <br />max <br />D = 13.70 <br />c <br />V - 5.22 <br />c <br />Fc = 0.25 <br /> <br />Ac = 16110 <br /> <br />v* = 1.15 <br /> <br />The dimensionless distance to mile 40.5 is (40.5/3.9) = 10.4. The <br />ordinate of the Qp/Qbmax curve at V* = 1.15 and x* = 10.4 is interpolated to <br />be approximately 0.15 indicating the peak flow at mile 40.5 is 95800 x 0.15 <br />= 14400 cfs. The midpoint flow (at mile 40.5/2) is found to be 21737.5. <br />The reference flow is (.3 + 0.1 * 0.84) x 21737.4 - 8347.16 which produces a <br />reference depth of 10.05. This value is used Eqs. (32)-{36) to find a time <br />to peak at mile 40.5 of 16.21 hours. <br /> <br />The true K and m coefficients at mile 40.5 are 92.1 and 0.80, <br />respectively. These values and the peak flow value are substituted into <br />Eq. (30) to compute a peak depth at mile 40.5 of 11.98 feet. Finally, the <br />time of flooding is found to be 15.85 hours and the time to "deflooding" is <br />found to be 28.48 hours. <br /> <br /><0- <br /> <br />1-34 <br />
